Notes

1

Natural convection cooling.

2

Peak output current lasting less than 60 seconds with duty cycle less than

5%. During peak loading, outputs may go outside of total regulation

limits. Total peak power output is 35 Watts.

3

Figure is peak-to-peak. Output noise measurements are made across a

50MHz bandwidth using a 12” twisted pair, terminated with a 47µF cap.

4

Total regulation is defined as the static output regulation at 25°C,

including initial tolerance, line voltage within stated limits, load currents

within stated limits and output voltages adjusted to their factory settings.

Also, 0.5

≤I(A)/I(B)≤3 to maintain stated regulation. This does not apply to

the NFN25-7628.

5

The NFN25-7628 has separately regulated +12V and -12V outputs. The

loading condition in note 4 does not apply.

6

7

Derating curve is application specific for ambient temperatures > 50°C,

8

Caution: Allow a minimum of 1 second after disconnecting the power

before making thermal measurements.

This product is only for inclusion by professional installers within other

equipment and must not be operated as a stand alone product.

Mechanical notes

A

The ground pad of the mounting hole near P1 allows system grounding

through a metal stand-off.

B

To improve conducted noise, the ground pad of the mounting hole near

the output connector should be connected with the ground pad of the

mounting hole near J3. Use metal stand-offs attached to a common metal

chassis. This connection also significantly attenuates common mode

noise.

C A standard L-bracket and cover is available for mounting which contains

all screws, connectors and necessary mounting hardware. Details are on

page CHECK. Order part number ‘NFS40 COVER KIT’.
